That is your battery it self, acting up. Following the SMC reset I would recommend a single (one time) deep discharge. The deep discharge will reset the Battery values reported. Just leave your computer running till it shuts down by it self due to low power.

Assuming it is now charged… Hold Home & Power buttons for at least 45 seconds, see if it starts up normally. If not… Plug your iPad's USB cable into a computer with iTunes. Hold down the Home button [keep holding] and connect to your iPad. Keep holding the Home button until you see a screen telling you to connect to iTunes. iTunes should show you ...

I recently fixed a water damaged (actually it was baby saliva) smartphone that had stopped charging when plugged in. Just like you, I was quoted a significant fraction of the original purchase price to even look at it, so figured there had to be a better way. So a squirt of contact lubricant (WD40 in my case) went in the USB port. That was a few months ...

Considering you're likely out of warranty anyway, depending on where you live, you could use a third-party repair shop. I've had mixed results with repair shops, but I have found one where I live which I would now trust to repair my MBP. In my case, this is a place that only deals in refurbished equipment. Unlike another 3rd party Mac shop whose main ...

If you have any warranty from Apple on the MB you should know that once your computer is "marked" with water damage the warranty voids. They even have a white thingy inside all the MB's that gets yellow when it touches any liquid - if they open the laptop and it's yellow - there goes your warranty. I would say the best way is to get a new battery and ...

You're lucky to have gotten off so lightly. Apple will quote high prices for water damaged items as they can't predict the severity of the damage. Replace the battery and your MacBook should be fine. I did a battery replacement a couple of years back for a friend who'd spilled whiskey over his trackpad. The whiskey had penetrated the battery causing the same ...

I would say that you would need to go ahead and use the Genius Bar option to repair your computer. My reasoning is that water damage can cause errors in strange ways that, upon first glance, seem to be straight forward, but are in fact impossible to properly diagnose without professional diagnostic equipment. For example, in your case, I doubt that the ...

I keep fully charging my iPhone 4s and using it throughout the day. Every couple of days my phone is dying at 7% 20% etc. I have researched this and many people are experiencing the exact same thing. The same percentages and are fully charging it! I think it is just a problem with iPhone 4s'due to reasearch. My phone was second hand and off eBay and someone ...

Problem Solved The battery was fine and the problem was with the charger. It seems that the charger couldnt transmit enough power to charge the computer while it was in use. I opened the casing of the charger and observed that 2 capacitors were swelled. I changed them with new ones (I found then in a video receiver). Now its working like the first day I got ...

The problem is with your MacBook A1278 A1286 MagSafe DC-In Power.

Looks like its time to replace the battery unfortunately. Will cost $99USD. Check out this link to attempt to resolve or diagnose the issue further first though: https://www.apple.com/support/ipad/repair/battery-power/

It could simply be the battery in the iPad no longer holds a charge due to age and cycles. You may try to replace the battery yourself: https://www.ifixit.com/Guide/iPad+3G+Battery+Replacement/3186

You should first make a full backup and restore the new iPhone to factory default. Don't worry about your settings, it's stored in the backup so you can place it back if you miss something. Or you could try this fix on the iPhone 5 first. Problem resolved? If the problem is gone you shouldn't place the back-up back, as something might be damaged inside. You ...

I think it's always best to go straight to the source: http://www.apple.com/batteries/ There are a lot of myths that come with batteries. It used to be the case that you shouldn't charge a device until it was completely discharged—that the more you drain to 0%, the better it is on the battery. In reality, there are all sorts of strange theories, but if you ...

Accountsd and cloudd manage iCloud. There's an insanely annoying bug which lots of people have where a sign into icloud password prompt comes up every few seconds and you can't sign out of find my phone.

Ok, so I found out how to fix the battery. You need to power off the computer, hold Shift+Control+Option+Power (at the same time) for a couple of seconds, then turn the computer back on. When you do that, the X should be gone! :)

The typical process of charging a battery: First the system detects the power plug. Now the Battery status is evaluated and and the battery circuit determines the amount of current to draw. It is not like a hose, it is a calculated current amount. In other words the battery is the boss and only takes what it needs without overheating or damage. If you ...

This is only educated speculation, but I imagine it's related to the amount of switching that has to take place when changing from battery power to being on the mains. The electrical input needs to be registered, the hardware switched from running off battery to a charging state if needed, and time for the kernel to be informed of the state change based on ...

The battery wears the least when it is kept at around 40% charge. Unfortunately, for most laptops there is no way to do this, the OS simply doesn't give you that option. Keeping it plugged in will certainly put wear on the battery, though it is not clear if that will wear it faster than always cycling, charging/discharging.

Actually, I have heard anecdotal evidence that removal of the battery does cause the system to throttle the CPU under certain circumstances. I also believe this can cause the kernel task to "absorb" the theoretical CPU capacity that would be there if it were running at full frequency. The steps to isolate this would be to monitor the internal temperatures ...

Status says 'Check Battery'. Looks like time for a new one, maybe? Potential cycle count for that machine is 1000, & you're pretty near that figure. Source: Mac notebooks: Determining battery cycle count

One troubleshooting step is to see which files are being modified while kernel_task is consuming 500% CPU. In Terminal: sudo fs_usage -f filesys You will see a lot of files fly by. Just scroll up to get an idea of what files are being written or read.

No, it is probably not normal. You can hold the alt key and click on your battery icon. Then click Condition: X. What is your X? You can read some more information based on the window that popped up By the way, does it really take 6.5 hour to charge to 100%? Cause it could just be some temporary mess-up with the estimation.

Pro-tip: Use an iPad charger on your iPhone and it will fill up 2x as fast.

That article is focusing on the possible dangers of starting a fire if not original components are used. Now you can ignore it and continue using non apple hardware at your own risk (usually small but it can happen), or use OEM hardware that is designed to prevent overheating (over-current) and it will shut down before serious stuff occurs. Definitely do ...

There is a circuit board on the battery it self that reports it presence and status to the OS X. In OS X there is a piece of hardware run by firmware called System Management Controller (SMC) that takes that information and process it. Sometimes the SMC gets confused and needs to be reset following instructions from Apple. You can also look up your Battery ...

The hardware that reads the battery health is independent of the OS running so it's just a coincidence that the X appeared with the update. I would get on the phone with AppleCare (or on the web or in a store) and see if they can run some remote diagnostics and tell you what precisely is happening with the battery. You can also get many details from System ...

This loop only happened when plugged into my MacBook Pro. When I plugged into a mains charger, it successfully booted to the OS... Weird.
